I would like to understand how thrust contributes to verticle lift. How much thrust do my legs have to produce to lift me 1 meter off the ground or 10 meters or 100 meters etc. What is the formula that will tell me Xthrust will propel Xkilos from the ground Xheight.

Ther are various ways to produce thrust some of them are
1. Use external force as in your case.
2. Vary the mass (Rockets)
3. Vary the pressure (Air planes )
The 3rd one is very tough to understand. One simplication is to use the Von-Karman's equation. Actually the correct solution is to obtain the general diff. equation using Reynold's Equation.
As for ur case I can only calculate the impulse or momentum
Suppose u want to fly 'h' metre then U should have a initial velocity
v= sqrt(2gh)
momentum to be transferred = ur mass * v
thrust = momentum / time required to deliver the momentum

Thrust is basically the same as force. Without getting into aerodynamics or NASA stuff, the amount of thrust required to send you 1 meter (vertically) into the air is the amount of force (F) required to overcome acceleration due to gravity (A), which is acting on your mass (M).
The equation for force (due to gravity) is F=M*A

You need alot of math and physics, no way to explain in one sitting, nice try though.
